Technically it opened last night, but as far as the posters are concerned “The Amazing Spider-Man” opens today, and will dominate the box-office conversation until “The Dark Knight Rises” lands the weekend after next.

Was a full reboot necessary? Not really, even though “Spider-Man 3” did seem to tie off the story Sam Raimi and Tobey Maguire were telling … or maybe it’s just that the last third of that picture is so enervating that their interpretation run out of gas while you’re sitting there watching. Still, a fourth film set within that universe — with different leads, but maybe with J.K. Simmons as J. Jonah Jameson and Rosemary Harris returning as Aunt May — wouldn’t have been too difficult to accomplish.

Instead, we start again from zero, much like J.J. Abrams’ “Star Trek”, though without the time-travel gimmick. And as I said in my review, if Sony has to keep making these movies — and they do, because otherwise the characters revert to Marvel and Disney gets to fold the web-head into the “Avengers” sequel — this is as good a way to go as any. Especially with Emma Stone as Gwen Stacy; I’m not sure how the love interest who doesn’t fight crime or turn into a nine-foot-tall reptile is the most present in the movie, but she’s just that good.

So, yeah. Spider-Man’s starting over. And it’s nice to have him back.
